The move is the result of the Cleveland Browns’ failure to conduct concussion tests on quarterback Colt McCoy on the sideline Dec. 8.

The trainers will be compensated by the NFL and approved by NFL Players Association, league spokesman Greg Aiello told ESPN.

The trainer will have only one assignment: making certain that the medical staff on each sideline follow protocol for concussion testing.

During the game, the trainers will be situated in an upstairs booth with direct communication access to each team's sideline.

CBS’s Charley Casserly first reported the news.
